I'm setting up a new network of Q2A sites and was planning to use Wordpress Multisite as the foundation. So I've successfully set that up. I want each site on the network to have its own Q2A functionality. So, site1.domain.com might have questions about apples, whereas site2.domain.com might have questions about oranges. Wordpress user accounts would allow people to be members of both sites.

What's the best way to install and integrate? To be clear, I'm not wanting qa.domain.com to be different than site1.domain.com, but for qa to be integrated into each site on the network. I haven't installed Q2A just yet, because the instructions seem to be focused on this scenario rather than mine.
